[0002] When producing gel paste, it is necessary to test the prepared flowing gel paste. At this time, the viscosity of the gel paste is about 5000CPS. When testing the paste, its content, pH value and other information are tested to ensure that the finished products produced later meet the relevant standards.

[0003] The sampling port of the preparation system is fixed in the preparation tank. In order to ensure the uniformity of the gel cream mixture inside the tank, it is generally necessary to sample and test the gel cream at different heights and positions in the tank. The traditional sampling method at this stage is to use a spoon for sampling, which is more laborious when performing deep sampling and the sample layers are easily mixed, so accurate analysis cannot be performed and the quantity and location requirements of process research sampling cannot be met.

[0006] The three cavities are each provided with a sample storage device for storing semi-solid glue and preventing the glue from flowing back.

[0007] As a preference, the sample storage container is divided into an inlet portion, a straight tube portion and a cavity bottom portion from the cavity outlet to the bottom;

One side of the silicone lining is attached to the outer surface of the outer chamber body, and the outer periphery of one side of the silicone lining is designed with rounded corners.

[0010] Preferably, the inlet and outlet have an arc-shaped profile and are smaller than the outlet end of the sample storage container;

[0011] The outlet ends of the cavity and the sample storage container are both trumpet-shaped and the inner bottom walls are arc-shaped.

[0012] Preferably, the inner wall of the inlet portion is installed with a protruding structure for simplifying the operation of pulling out the sample storage device along an inclined direction. The inclination of the protruding structure is consistent with the inclination of the cavity, and the protruding structure is in a diamond shape that is narrow at the top and bottom and thick in the middle.

[0013] Preferably, an electromagnet for attracting the magnetic block is installed on the inner bottom wall of the extended handle, and a battery structure and a control circuit for controlling the on and off of power to the electromagnet are arranged inside the extended handle.

[0018] Preferably, a steering handle is installed on the outer surface of the outer compartment body, and a baffle bar for calibrating the accuracy of the overlap between the inlet and outlet and the cavity is installed on the steering handle.

[0019] By means of the above technical solution, the present invention provides a temperature-controllable quantitative sampler for semi-solid materials, which has at least the following beneficial effects:

[0021] 2. When the sampling module of the present invention rotates, the semi-solid glue on the surface of the silicone ring can be scraped into the range of the inlet and outlet. In addition, when the sampling module is rotated in conjunction with the silicone lining, the sample contaminated on the inner wall of the outer bin inside the sample storage device is scraped back into the sample storage device, and the gap between the sample storage device and the inner wall of the outer bin body is reduced, effectively avoiding the sample inside the closed sample storage device from leaking along the gap between the two, thereby effectively avoiding the sample from remaining on the inner wall of the sampling module and reducing the difficulty of subsequent cleaning.

[0023] 4. The temperature control design of the present invention can ensure that the sample inside the sample storage container always maintains a flowing viscous paste form, avoiding the situation where the sampled material cannot be detected and analyzed due to solidification after cooling. In addition, it can ensure that the sampled material inside the sample storage container is evenly heated to avoid the presence of agglomerates.

[0024] 5. The present invention can improve the accuracy and efficiency of the sampling module when one side of the cavity is adjusted to coincide with the inlet and outlet of the outer chamber surface, thereby ensuring that the sample enters the sample storage container accurately and quickly.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The traditional sampling method for semi-solid glue liquids such as gel creams is to use a spoon to take samples, which is more laborious when performing deep sampling and the sample layers are easily mixed, making it impossible to perform accurate analysis and unable to meet the quantity and position requirements of sampling for process research (it is necessary to sample and test the gel paste at different heights and positions in the tank to evaluate its mixing uniformity). Ordinary samplers are not suitable for sampling at different positions of flowing viscous semi-solids (such as pastes), and it is not convenient to take out the viscous semi-solids (such as pastes) taken by the sampler; viscous semi-solids (such as pastes) have a certain viscosity, which is time-consuming to clean and difficult to wash; in the process of process research, multiple continuous sampling is required to monitor the mixing of materials at all times to facilitate the decision whether to continue with subsequent processes. At this time, it is necessary to use a sampler for multiple sampling, and the sampler needs to meet the requirements of quick cleaning and drying. In order to achieve the one-time removal of materials at different depths in a semi-solid glue solution and effectively prevent the side leakage and backflow of the sampled glue solution, please refer to the implementation methods disclosed in the following embodiments 1 to 4.

[0036] Embodiment 1

[0037] To solve the problem of mixing of gels at different depths during semi-solid gel sampling, please refer to Figure 1-Figure 7The present embodiment proposes a temperature-controllable quantitative sampler for semi-solid materials, comprising an outer warehouse body 1, an extended handle 2 installed on the top of the outer warehouse body 1, and a sampling module 3 located inside the outer warehouse body 1. The outer surface of the sampling module 3 is provided with at least three cavities 301 arranged in an upper and lower manner. A magnetic block 302 is installed on the top of the sampling module 3 for increasing the connection stability between the outer warehouse body 1 and the extended handle 2. The outer wall of the outer warehouse body 1 is provided with inlets and outlets 101, which are the same in number as the cavities 301 and are interconnected. The interiors of the three cavities 301 are all provided with sample storage devices 4 for storing semi-solid glue and preventing the glue from flowing back. In the sampler, the sampling module 3 is inserted into the interior of the outer warehouse body 1, and the extension handle 2 is detachably combined with the outer warehouse body 1, and then the sampler is inserted into the interior of the semi-solid glue, and the extension handle 2 is controlled to drive the sampling module 3 to rotate inside the outer warehouse body 1, and the port of the sample storage 4 is adjusted to a state of coinciding with the inlet and outlet 101. At this time, the semi-solid glue around the sampler enters the interior of multiple sample storages 4 at different depths, so as to achieve the purpose of sampling. After that, the extension handle 2 is controlled again to drive the sampling module 3 to rotate 90°-270° inside the space of the outer warehouse body 1, so as to adjust the port of the sample storage 4 to a state of mutual displacement with the inlet and outlet 101, and the inner wall of the outer warehouse body 1 is used to close the port of the sample storage 4 after sampling, so as to effectively avoid the mixing of the sample taken. The size of the sample storage 4 is set according to the sampling requirements, so as to achieve the purpose of quantitative.

[0038] After the sampler is inserted into the semi-solid glue, the sampling module 3 is rotated to facilitate the sample to enter the space inside the sample storage 4. The area where the outer surface of the sampling module 3 overlaps with the inlet and outlet 101 will be contaminated with the semi-solid glue. In order to effectively reduce the residual amount of the semi-solid glue on the outer surface of the sampling module 3, as shown in 1, Figure 2 , Figure 5-Figure 7 It is shown that a silicone ring 1011 for scraping the semi-solid glue on the surface of the sampling module 3 is installed on the inner side of the inlet and outlet 101. The silicone ring 1011 has a certain elasticity, which reduces the gap between the sampling module 3 and the inner wall of the outer chamber body 1 near the inlet and outlet 101. When the sampling module 3 rotates, the semi-solid glue stained on its outer surface can be scraped by the silicone ring 1011 to the range of the inlet and outlet 101, thereby effectively reducing the residual amount of the sample on the inner wall of the sampling module 3.

[0039] like Figure 4As shown, the sample storage 4 is divided into an inlet portion 401, a straight cylindrical portion 402 and a cavity bottom portion 403 from the outlet end of the cavity 301 to the bottom. The inclination of the cavity 301 and the sample storage 4 is not less than 30°, and the maximum inclination can be set to 75°. The inclined sample storage 4 is more convenient for the glue to flow downward along the inclined surface of the sample storage 4. In addition, the semi-solid glue will flow downward more easily under the surface tension of the inclined sample storage 4, thereby accelerating the speed of the semi-solid glue entering. In addition, after the glue inside the sample storage 4 reaches a certain height, the angle of inclination can make the glue flow downward to the bottom of the device, effectively preventing the glue from flowing back due to gravity.

[0040] When the sample reservoir 4 is filled with samples and the port is closed, the semi-solid glue that is about to overflow from the port of the sample reservoir 4 will contact the inner wall of the outer chamber 1 and cause residue. In order to solve the problem of residue on the inner wall of the outer chamber 1 caused by the overflow of the sample reservoir 4, as shown in FIG. Figure 4-Figure 6 As shown, the inlet part 401 includes a hard ring body 4011 and a silicone lining 4012 installed on the straight tube part 402. The silicone lining 4012 is arranged on the inner wall of the hard ring body 4011 and wraps the side of the hard ring body 4011 away from the straight tube part 402. One side of the silicone lining 4012 is attached to the outer surface of the outer warehouse body 1 to reduce the gap between the outlet of the sample storage container 4 and the inner wall of the outer warehouse body 1. The outer periphery of one side of the silicone lining 4012 is rounded to improve the smoothness of the sample storage container 4 when the sampling module 3 rotates after the sampling is completed. The application of the silicone lining 4012 reduces the gap between the sample storage container 4 and the inner wall of the outer warehouse body 1, and effectively avoids the sample inside the closed sample storage container 4 from leaking along the gap between the two. In the process of rotating the sampling module 3, the part of the sample inside the sample storage container 4 that remains on the inner wall of the outer warehouse body 1 can be scraped by the silicone lining 4012 to be gathered back into the sample storage container 4.

[0041] The profile of the inlet and outlet 101 is arc-shaped and smaller than the outlet end of the sample reservoir 4, which effectively prevents the semi-solid glue in the sample reservoir 4 from leaking sideways. The outlet end of the cavity 301 and the sample reservoir 4 are both trumpet-shaped and the inner bottom wall is arc-shaped, which is used to reduce the residue of viscous semi-solid in the dead corner of the cavity and facilitate cleaning and drying.

[0042] Embodiment 2

[0043] When the sampled semi-solid gel is tested, the sample storage container 4 containing the sample needs to be taken out from the sampling module 3. Figure 4-Figure 5As shown, the inner wall of the inlet portion 401 is provided with a protruding structure 4013, the inclination of which is consistent with the inclination of the cavity 301, and is used to simplify the extraction operation of the sample storage 4 along the inclined direction. The protruding structure 4013 is in a diamond shape with narrow top and bottom and thick middle, so as to reduce the sample content remaining on the protruding structure 4013 when the sample storage 4 discharges the sample. The outer compartment 1 is placed horizontally with the inlet and outlet 101 facing upward, and then the extended handle 2 is pulled toward one side, so that it drives the sampling module 3 and the sample storage 4 to be extracted from the inside of the outer compartment 1. Then, through the cooperation of the tool, the protruding structure 4013 is clamped to drive the sample storage 4 to be pulled out along the inclined extension direction. During the process, the port of the sample storage 4 is always horizontal, so that the semi-solid glue sampled can be prevented from being splashed out.

[0044] Embodiment 3

[0045] Compared with the traditional method of using a spoon to sample semi-solid glue, it takes a little longer to take the semi-solid glue from the production device to the detection area. During the process, the semi-solid glue is easy to solidify due to cooling. Based on this, in order to effectively avoid the problem that the sampled semi-solid glue solidifies due to cooling and affects the detection and analysis. Figure 2-Figure 3 , Figure 5 As shown, a battery structure 202 and a control circuit 203 for controlling the on and off of the electromagnet 201 are arranged inside the extended handle 2, a liquid storage chamber 303 is arranged inside the sampling module 3, a heating structure 304 for increasing the temperature of the liquid is installed on the inner wall of the liquid storage chamber 303, and a thermistor 305 for measuring the temperature of the liquid is installed inside the liquid storage chamber 303. When sampling, the battery structure 202 and the control circuit 203 are used to power the heating structure 304 electrically connected thereto, and the heating structure 304 converts electrical energy into thermal energy, and transfers the thermal energy through the liquid water loaded inside the liquid storage chamber 303. Since liquid water has good thermal conductivity, high specific heat capacity and convective heat transfer capacity, the sample placed in the sample storage device 4 inside the cavity 301 can be heated evenly, thereby effectively avoiding the cooling and solidification phenomenon, thereby ensuring the accuracy of subsequent detection. In addition, the actual temperature of the liquid water inside the liquid storage chamber 303 is measured in real time by the thermistor 305. According to the characteristics of the product, the temperature range is set to 50-90°C to ensure that the product will not cool down, solidify or overheat.

[0046] Before and after using the sampler to take samples, the relative position relationship between the sampling module 3 and the inlet and outlet 101 in the outer chamber 1 needs to be adjusted, such as Figure 2 , Figure 3 and Figure 6As shown, the inner bottom wall of the extended handle 2 is installed with an electromagnet 201 for attracting the magnetic block 302. By issuing instructions to the control circuit 203, the control circuit 203 starts the battery structure 202 to power the electromagnet 201. The electromagnetic coil in the electromagnet 201 receives the current and generates a magnetic field, which can firmly adsorb the magnetic block 302, so that it is convenient to drive the sampling module 3 to rotate along the inner wall of the outer chamber body 1 when the extended handle 2 is subsequently toggled, thereby achieving the purpose of convenient adjustment of the opening and closing of the sample storage port 4.

[0047] like Figure 1 and Figure 2 As shown, the outer surface of the extended handle 2 is embedded with a display screen 204 for displaying the temperature of the liquid in the liquid storage chamber 303 and the remaining power of the battery structure 202, so that the user can timely understand the temperature information of the solid glue when it is heated and the power information of the battery structure 202, so as to make corresponding adjustments to the displayed information in a timely manner. The top wall and bottom wall of the concave part on one side of the display screen 204 are inclined, and the four corners of the concave part are arc-shaped, which is used to reduce the cleaning dead angle. An annular groove 102 is provided on the outer surface of the outer warehouse body 1, and an outer ring 205 is integrally installed on the outer surface of the extended handle 2. A snap ring adapted to the annular groove 102 is installed on the inner wall of the outer ring 205. The snap ring is made of rubber material and is embedded in the annular groove 102 to increase the stability of the connection between the extended handle 2 and the outer warehouse body 1. The outer side of the snap ring is arc-shaped. When controlling the extension handle 2 to rotate relative to the outer warehouse body 1, the resistance encountered by the snap ring when it follows the rotation inside the annular groove 102 can be reduced.

[0048] Embodiment 4

[0049] When the extended handle 2 is turned to drive the sampling module 3 to rotate along the inner wall of the outer chamber 1 and the sample storage 4 in the sampling module 3 is adjusted to be connected with the inlet and outlet 101, the opening of the sample storage 4 and the inlet and outlet 101 may be misaligned due to the rotation angle being too large or too small, which may cause the outer wall of the sampling module 3 to be contaminated with the semi-fixed glue, which is difficult to clean later. Based on this, in order to ensure the cleanliness of the sampling module 3 and the inner wall of the outer chamber 1, as shown in FIG. Figure 1 and Figure 2As shown, a steering handle 103 is installed on the outer surface of the outer warehouse body 1, and a baffle 5 is installed on the steering handle 103 for calibrating the accuracy of the overlap between the inlet and outlet 101 and the cavity 301. By holding the steering handle 103, a rotational force is applied to the extension handle 2. At this time, the electromagnet 201 is powered on, and a magnetic attraction is generated between it and the magnetic block 302, thereby driving the sampling module 3 to rotate relative to the outer warehouse body 1 until one side of the extension handle 2 contacts the baffle 5 and cannot continue to rotate. This indicates that one side of the sampling module 3 with the cavity 301 is adjusted to a state of overlapping with the inlet and outlet 101 on the surface of the outer warehouse body 1. In addition, since the caliber of the inlet and outlet 101 is smaller than the port of the sample storage container 4, it can effectively prevent the outer surface of the sample storage container 4 from being contaminated with the glue during the collection of the semi-solid glue.

[0050] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
